FLUSH BOX Application led August 23, 1929. Serial No. 387,887.

The present invention is a continuation in part of my application SerialNumber 217,192 filed September 2, 1927, which relates to flush boxes.

One of the main novel features of my invention resides in the provisionof a special construction on the bottom of the flush box whereby metalvalve seats are entirely eliminated.

Still another object of the invention resides in the provision of novelmeans for suspending the valve body from the operating lever so that itwill be rectilinearly guided into operative position without the use ofany fixed guides.

A further object is to provide a novel suspending means for the valvebody which may be readily adjusted to any size of tank.

vWith the above and other objects in view my invention consists in thenovel construction, combination and arrangement of parts as will behereinafter more fully described and defined in the appended claims.

In the accompanying drawing which forms part of this specification andin which similar reference characters denote corresponding parts, F ig.1 is a longitudinal vertical section of the ush box on line 1-1 of Fig.2 seen in the direction of the arrows; Fig. 2 is a cross sectionthereof; and Fig. 3 is a slight ly enlarged sectional view of a modiedconstruction of the flush valve seat.

Referring to the drawing more in detail, denotes the tank of the flushbox which is made preferably of porcelain, china or other suitablenon-corrosive material. rfhis tank is provided at its bottom with acircular opening 11, the edges 11EL of which are circularly rounded toform a valve seat. Below this seat is provided a hollow extension 10having a discharge opening 102 arranged in vertical alignment with thevalve seat 11a. IThis opening is conical or tapered and is adapted toreceive a spout 12 formed with a correspondingly shaped flange 12 at oneend and with an external thread 'l22 at its opposite end. The tapered:flange of said spout is tightened in the conical opening by means of arubber washer 13 or the like and a nut 13', while the external thread ofsaid spout serves for the attachment of a flush pipe leading from thetank tothe bowl (not shown).

The tank l() is also provided with an in tegral wall 14 extendinglongitudinally thereof at the rear of the valve seat V11a and formingwith the rear wall of the tank an overflow chamber. The bottom 15 ofsaid chamber terminates in the hollow extension 10 of the tank andcommunicates through a passage 16 with the space between the valveandthe discharge opening. The provision of this overflow chamber abovedescribed eliminatesleakage generally occurring at joints and because ofits comparatively large size avoids clogging through Vforeign matter orsediment. v

17 denotes the usual manual lever which isfulcrumed at 18 to the tankand which pro jects into the latter serving for the operation of theflush valve. The latter comprises a hemispherically shaped weightedvalve body 19 of rubber or the like which is provided centrally with avertically'projecting stem in form of a rod 2O of noncorrosive material,the upper free end of which is formed with a stop20 in form of a loop orthe like. V'llhe stem is suspended from said lever 17 by means of a wire21 or the like, one end of which is hooked-shaped and adapted to engageone of a series of perforatio-ns 17 pro- '30 j vided in said lever. rlhesaid wire 21 is coupled to stem 20'by means of acoupling bor; 22 whichis provided with two openings in which thewire 21 and stem 2O may slide.A set screw 23 adapted to project into the opening for wire 21 isprovided in order that the said coupling block may be positioned at anydesired point on said wirel 21, thus making the device adjustable fordifferent G6 sized tanks. The opening for stem 20 is so arranged withrespect to the opening for wire 21 that the stem 20 is in alignment withthe point of suspension of saidV wire from said lever 17 whereby thestem 20 will be er, capable of moving vertically relative to the member21 and be rectilinearly guided in said block. Thisstructure eliminatesfixed guides and thereby simplifies manufacture. .Y In Figs. Vl and 2the Valve seat is shown iov as formed integrally with the tank. Inwhichsaid valve body is freely suspended by stead, a valve seat of glass orother nonsaid suspending member whereby the latter corrosive materialmay be employed. In may be displaced vertically.

such case the opening in 11 is countersunk In testimony whereof I affixmy signature. as at 1lb and valve seat 24 in the form of JOSEPH WERNER.

a ring with the rounded valve seat edges 24a is adapted to be cementedor otherwise fixed in the said countersunk portion 11b of said opening.The other structure remains the same. lVith my improved tank and Yeither the integrally formed or inserted glass seat I have provided anon-corrodable permanent structure in which metal has been eliminatedentirely. v

It is obvious that my construction may be modified in various wayswithout departing from the spirit of my invention. I therefore do notwish to restrict myself to the details shown and described. Y

What I claim is l. In a flush box, a tank having a discharge port in itsbottom, a valve for controlling said port comprising a valvek seat whichis independent of pipe leads to said port, a valve body cooperating withsaid seat and having a rigid'stem projecting therefrom, `a stop at thefree endof said stein, a connecting block slidably mounted on said stem,a connecting member adjustably connected to said block and provided atits free end with a suspendinghook so bent as to have the suspendingpoint-of the hook in axialalignment with said stem and means in saidtank from which said valve body is freely suspended whereby the' lattermay be displaced vertically.

2. In a flush box having a tank with a dis- Y charge port at its bottom,a valve for controllingy said port, said valve including a valve body.adapted to close said port, said body having a rigid stem projectingtherefrom, a stop at the free end of said stem, a connecting blockslidably mounted on said stem, a connecting member slidably mounted insaid block, setting means for fixing said member at a given position insaid block, said member being provided at its free end with a suspendinghook, .so bent as to have the suspending point of the hook in axialalignment with said stem and means in said tank from which said valvebodyis freely suspended whereby the latter may be displaced vertically.

3. In a flush box, a tank having a discharge port in its bottom, a valvefor controlling said port comprising a valve scat, a valve bodycooperating with said seat and having a rigid stem projecting therefrom,a connecting block slidably mounted on 'said stem, a connectingmemberadj ustably connected to vsaid block and provided at its free endwith a suspending member so formed that'the suspending point thereof isin axial alignment with said stein and means in said tank from
